PERCUSSION-LOCK FOR BREECH-LOADING GUNS.

SPECIFICATION forming part of Letters Patent NO. 619,218, dated February7, 1899.

Application filed October 11,1898. Serial No. 698,225. (No model.)

To all whom it may concern.-

Be it known that LOARL POHLIT, a citizen of the German Empire, residingat Essen, Rhenish Prussia, Germany, have invented certain new and usefulImprovements in Percussion- Locks for Breech-Loading Guns, of which thefollowing is a specification.

My invention has reference to improvements in percussion-locks forbreech-loading guns, and in particular to improvements in looksembodying a spring-hammer located within the breech-block, and adouble-armed cocking-lever and a trigger, both pivotally held within arecess of the breech-block, the inner arm of the cocking-lever engagingthe hammer and the outer arm actuated by an arm of the trigger, so thatby pulling the hammer is first cooked and the outer arm of thecocking-lever then tripped, so as to release the hammer.

My improvements in such locks consist, essentially, in certain means, tobe described hereafter, whereby the hammer is returned from its positionafter firing directly to the position of rest without being first full-cooked' and then returned into the position of rest, thus requiringbut a very short motion of the hammer for this purpose. In thus movingthe hammer but a short distance a very small tension is placed on thehammer-spring and but a small force is required to bring the hammer intothe position of rest.

The nature of my invention will best be understood when described inconnection with the accompanying drawings, in Which-- Figure 1represents a side View of the breech end of a gun, parts of thebreech-block and mechanism being in section and the lock in the positionof rest. Fig. 2 is a horizontal section of Fig. 1. Figs. 3 and 4. aresimilar views showing the lock at full cock. Figs. 5 and 6 are similarViews showing the lock in the position after firing. Figs. 7, 8, and 9are detail views of the several parts of the firing lock.

Similar letters of reference designate corresponding parts throughoutthe several views of the drawings.

In the drawings, the letter G designates the gun; M, the breech-block;E, the hammer or firing-pin inserted into the breech-block, and

D the screw forlocking the breech, said screw being provided with acurved flange h.

B is the cocking-lever, andA the trigger. The cocking-lever B, as shownin detail in Fig. 7, has two arms Z and f and is pivoted to a pin 5,secured in the breech-block. The end of the inner arm Z of thecocking-lever B engages a notch of the hammer E and acts against the endface of this notch, as shown in Figs. 2, 4., and 6. The trigger A isshown in detail in Fig. 9. It is pivoted to the breechblock by a pin'd.The trigger has a flat flange or plate 2', an eye kfor attaching thelanyard, and an arm a, with a vertical perforation cylindrical at itsupper part and square at its lower end.

0 is the cocking-stud, placed into the perforation or recess of the armat. Its lower square end fits into the lower square part of theperforation, so as to prevent turning of the stud. A spring a is placedaround the stud between the square part of the perforation and ashoulder on the stud. This spring 6 tends to force the stud up againstthe full part of the outer arm f of the cocking-lever B, as shown inFigs. 5 and 6, or against the depressed part (1 of said arm, as shown inFigs. 1 and 2.

The hub of the trigger A has a flat part or face m, adapted to actagainst the side face 0 of the depressed part of the arm f of thecocking-lever 13, while the inner end 0 of the stud O is adapted toengage the face 11, Figs. 4 and 7, of the recess q in the arm f. Thecookingstud O at its upper end has a sloping notch 19, and the part 1"of the arm f is so formed as to cooperate with the notch 19 of the stud,so as to press the stud 0 into the recess of the arm a during theforward motion of the hammer in firing.

The operation of the firing-lock is as follows: The lock being in theposition of rest, Figs. 1 and 2, and the trigger being pulled by alanyard hooked into the eye 70, the trigger is turned on the pin (1,whereby the upper end 0 of the cocking-stud O is turned against the facea of the depression in the outer arm f of the cocking-lever B, so as toturn the cocking-lever to full-cock. As the cocking-lever reaches itsgreatest throw, Figs. 3 and 4, the position of the trigger and its stud0 being such that the sloped outer edge a of the arm f engages thesloped notch 19 of the cookingstud O, the latter is depressed throughthe action of the hammer-spring, so that the arm f is free to slide uponthe upper end face of the said stud 0, allowing the hammer to completethe forward stroke to the position shown in Fig. 6 by the action of thehammer-spring. During this motion of the hammer the cocking-lever iscarried along until the side face 0 of its depressed or thinner partreaches the straight face m on the hub of the trigger, as

shown in Fig. 6. In this position of the cocking-lever the full part ofits arm f holds the stud 0 within the perforation of the arm a. Whenafter firing the breech-screw is turned for opening the breech, the faceg of the curved flange h pushes the trigger from the position Fig. 6into the position Fig. 2, while at the same time the face m of the hubof the trigger bearing against the side face 0 of the arm f pushes thecocking-lever B into the position of rest, Fig. 2, without firstcarrying it to the position of full-cock. As the cocking-lever B reachesthe position of rest the head 0 of the cocking-stud O has reached aposition opposite the depressed part q of the arm f and the stud entersthe depression. The several parts of the firing-lock are then again inthe positions shown in Fig. 1. It is evident that repeated cooking ofthe firinglock may be effected by moving the trigger forward from theposition Fig. 6 direct by hand or by the lanyard hooked into the eye It.

What I claim as new is In a firing-lock for breech-loading guns of thecharacter specified, the combination of the breech-block, thespring-hammer E, the double-armed cocking-lever B, the trigger A havinga perforated arm a, cocking-stud O and spring located within theperforation of the arm (1, arranged and operating substantially asdescribed.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
